first time jeep owner and i want to change the oil whats a good oil the jeep people use because in my 91 sentra se-r we swear by mobil 1 just trying to get a feel thanks for reading

Rotella T6, better and cheaper than Mobile 1. I swore by Mobile 1 until I got a Jeep.

Good writeup on oil right here.

Wow. That is a loaded question. There are posts for miles on oil opinions, all different. I read that massive oil post from the link above last week. Very interesting and I'm going to try the rotella t6 next time.

Rotella T6 and WIX filters=happy jeep

X2, I run T6 5w40 year round. Right now I have a Motorcraft FL-1A filter ("oversized" and an excellent filter for the money) on it (The Wix51515/NAPA1515 are good options as well). In the winter I usually run a NAPA Gold (WIX) 1459 (WIX 51459), which is even larger (it and the Baldwin B7311-MPG are pretty much the biggest filters that fit) for the extra surface area (and at least theoretically better flow).

Shell Rotella T6 5w40
Pennzoil (yellow bottle) 5 or 10w30
Castrol Edge 0w30
Mobil 1 0w40


My top recommendations. I personally ran T6 for a few sessions to clean things out a bit and am now running PYB 5w30.

Havoline 40W.

thanks for the response rotella t6 is onsale at walmart and i get 10 percent of from working there so thats a plus

might as well ask spark plugs we swear by ngk in nissans so whats do jeeps like and please add the part number thanks for reading

I run Driven 10W40 synthetic hot rod oil from Joe Gibbs Racing. I wouldn't recommend it for a stock motor, though.

Jeeps (the 4.0L I6 specifically) like copper plugs (and will generally run better on them than platinums), either NGK (part# ZFR5N) or Champion (part# RC12LYC in 99 and older or RC12ECC in any model year) both work well.

Stick with NGK coppers on your Jeep also.

That's way too thick.

I run castrole gtx high milage 10w 30

Will this Rotella T6 5w40 with the WIX filter and these NGK plugs work on 2001 year model okay?
Also, could you check out my differential pics I posted, compared to the pics you posted. I'm having a hard time telling which ones.

Not trying to steal the thread, just need your thoughts. Thanks!

NAPA Gold filters are also made by WIX as well as there NASCAR Racing filters I run both of them or WIX always. As well as Rotella in my XJ and Castrol Full Syn in everything else.

Advance auto 20w50 and wix filter..

Not trying to hijack the thread but the Rotella T6 that I find says it is for Diesel engines. Is this the same stuff your all using or is there a different one for gas engines?

Yes. It is not solely for diesel it is also for gasoline commercial fleets and industrial engines.....good stuff!

Rotella has a copious amount of zinc additives that are engines need, newer engine oils are lacking what our Tractor engines need. Run the Dino for 12 bucks a gallon from menards with a wix 50505 mustang filter. With the extended filter the you need about 6 quarts.

I can't find this WIX # 50505. Is that the correct part number?

He meant 51515. It is a little longer than the stock filter but otherwise identical. Some people believe this is advantageous. I'm not convinced, but it costs the same and does no harm, so as long as I haven't disproven its usefulness, I also use this size in the event it does provide some sort of benefit.

Our engines are far from being tractor engines, and that stupid analogy helps no one. It's misleading and it is neither clever nor cute. It is true that, overall, oils have less ZDDP than they once did, but that isn't the only thing that has changed with time, and they don't need to have as much as they once did even for flat-tappets like ours. If they did, PYB would be garbage in a 4.0, but it is one of the best choices to be made. If I remember, I'll link an SAE document that debunks the ZDDP myth/misconception later when I get home.

50 weight is pointlessly thick. Enough said really. 30 is plenty and factory spec. 40 is fine but has been shown to have no advantages inherent to its thicker viscosity. Oils that are good for the 4.0 and are also 40's are good because they're good oils, not simply because they're 40 weight.

T6 is a diesel oil but is also a gas oil--same product.

I use this http://www.commaoil.com/passenger-ve...iew/171/XTC5L/ which seems to do the job and has 0.12% Zinc (not sure what the rest of the spec means!) although recently I've noticed the oil pressure at hot idle is falling off a bit (about 1.5 bar/21 PSI) but it's definitely time for a change. I'll be interested to see if new oil/filter makes any difference.

Will this Rotella T6 5w40 with the WIX filter and these NGK plugs work on 2001 year model okay?

Yes

thanks for the info you guys are great and dont worry about high jacking the thread its not a problem we are all here as a jeep family so six quarts of rotella t6 ngk copper spark plugs a wix oil filter means happy jeep gotcha and again thanks for the info

High zinc content reduces the life of your catalytic converter, which is why it was reduced in modern oils. You don't need additional zinc for a stock motor. They last just fine with the reduced zinc found in off-the-shelf motor oil.

You do need it if you're running a non-stock cam. When they first reduced the amount of zinc in the oil, there was a rash of camshaft failures in strokers where the extra stress on the more aggressive cams was causing them to wear out. The zinc helps protect them. The oils were tested for mainstream engines and found to be okay, but the strokers were outside of spec and therefore outside of the test parameters.

If you don't have a stroker or aftermarket cam, don't worry about it.

Very interesting info here. I would have never known had it not been for the info presented here today. Thanks!

cheapest 5w30 i can find

and always a fram filter

change oil and filter once a year

Now why'd you have to do that?

pre internet, i bought the cheapest filters i could find, usually fram

then the internet has a hard on against them, so i use them exclusively

zero issues.

In the XJ I normally run 10w-40 Phillips TropArtic and either a Baldwin or Wix filter (depending on which shop I buy through).

That is more of an issue with newer vehicles that have much denser catalytic converters than something as old as an XJ. When the XJs were built every bottle of oil on the shelf had as much or more zinc than Rotella. It really shouldn't have any significant effect on you cat unless you're burning a lot of oil (in which case the cat won't last long no matter what you use).

Why? Even if you don't believe all the "horror stories", there are much better filters out there than Fram for the same price or less (Purolator Classic, Motorcraft, Napa Silver, etc.).

better?

my motors will last 30-40 yrs regardless

I use semi synthetic valvoline max life , with a mopar oil filter .

This engine was used in some International Harvesters! Sounds tractor to me.

Technically the AMC I6 was used in IH 4000 series Swathers, not quite a "tractor" but definitely agricultural.
